POV (Persistance Of Vision) using ATtiny2313

POV (Persistance Of Vision) using ATtiny2313

A simple POV using ATtiny2313 without any hall effect sensor, Simple Circuit and simple programing logic.

Circuit Diagram :

Circuit does not consist of any programing pin out, take ISP pins out and use USB AVR programmer
 for programming .hex file in your ATtiny2313. Power input must be regulated 5V

Source Code: (hex, .c , makefile, picture converter)
